EnumSetis a high-performanceSetimplementation for enum types. All of the members of an enum set must be of the same enum type. Internally, it is represented by a bit-vector, typically a singlelong. Enum sets su
Like the core Java implementation, any attempt to modify the created immutable instance will throwUnsupportedOperationException. Now, let’s explore different ways of creating immutable instances. 5.1. UsingImmutableSet.copyOf() Simply put, theImmutableSet.copyOf()method returns a copy of all the el...
attempting an operation on an ineligible element whose completion would not result in the insertion of an ineligible element into the set may throw an exception or it may succeed, at the option of the implementation. Such exceptions are marked as "optional" in the specification for this interface...
Basically, if you need to set a large number of bits, or bits at extremely high offsets, you probably want to use this Sparse BitSet. All other alternatives are essentialy off the table; the Java BitSet class is a non-starter. Performance is superior in almost all cases to the standard...
All general-purpose sorted set implementation classes should provide four "standard" constructors: 1) A void (no arguments) constructor, which creates an empty sorted set sorted according to the natural ordering of its elements. 2) A constructor with a single argument of type Comparator, which ...

Note that this implementation is not synchronized. If multiple threads access a hash set concurrently, and at least one of the threads modifies the set, itmustbe synchronized externally. This is typically accomplished by synchronizing on some object that naturally encapsulates the set. If no such ...
